N2 - QCD with infinite heavy quark masses exhibits a first-order thermal transition which is driven by the spontaneous breaking of the global Z3 center symmetry. We analyze the corresponding order parameter, namely the Polyakov loop and its moments, and show, with a rigorous finite size scaling, that in the continuum limit the transition is of first order. We show that the use of a parallel tempering algorithm can significantly reduce the large auto-correlation times which are mainly caused by the supercritical slowing down. As a result, we calculate the transition temperature w0Tc with per-mill precision, and the latent heat, carrying out controlled continuum and infinite volume extrapolations.
